Boron Proxies in Paleoceanography and Paleoclimatology
Anthropogenic carbon dioxide emissions do not only warm our planet but also acidify our oceans. It is currently unclear to which degree Earth’s climate and marine life will be impacted by these changes but information from Earth history, particularly the geochemical signals of past environmental changes stored in the fossil remains of marine organisms, can help us predict possible future changes. This book aims to be a primer for scientists who seek to apply boron proxies in marine carbonates to estimate past seawater carbonate chemistry and atmospheric pCO2. Boron proxies (δ11B and B/Ca) were introduced nearly three decades ago, with subsequent strides being made in understanding their m...
Historical Greenhouse Gas Concentrations for Climate Modelling (CMIP6)
Abstract. Atmospheric greenhouse gas (GHG) concentrations are at unprecedented, record-high levels compared to the last 800 000 years. Those elevated GHG concentrations warm the planet and - partially offset by net cooling effects by aerosols - are largely responsible for the observed warming over the past 150 years. An accurate representation of GHG concentrations is hence important to understand and model recent climate change. So far, community efforts to create composite datasets of GHG concentrations with seasonal and latitudinal information have focused on marine boundary layer conditions and recent trends since the 1980s. Here, we provide consolidated datasets of historical atmospheri...
Phosphorus Pollution Control
Phosphorus Pollution Control – Policies and Strategies Deterioration and decline of water resources due to pollution caused by humans and their activities has become a universal health, environmental, social and economic problem. Excess discharges of nutrients, in particular, phosphorus, has been recognized as the most prevalent water pollution problem globally. Moreover, its perpetual occurrence and expansion creates imminent threats to water and food security. Despite extensive research during the past five decades, many key questions in eutrophication science remain unanswered. This book summarizes the most recent policies and strategies for phosphorus removal and recovery from municipal, residential and agricultural wastewater effluents and runoff into a concise and up-to-date volume. The book will be of interest to environmental and water resources scientists and engineers, consultants, policy makers, and practitioners working in the field.
Amino Acids and Proteins in Fossil Biominerals
AMINO ACIDS AND PROTEINS IN FOSSIL BIOMINERALS An essential cross-disciplinary guide to the proteins that form biominerals and that are preserved in the fossil record?? Amino Acids and Proteins in Fossil Biominerals is an authoritative guide to the patterns of survival and degradation of ancient biomolecules in the fossil record. The author brings together new research in biomineralization and ancient proteins to describe mechanisms of protein diagenesis. The book draws on the author's experiences as well as current information from three research fields: geochemistry, archaeology and Quaternary sciences. The author examines the history of the study of ancient proteins, from the dating of Qu...
